    • A method of and system for time-division-based channel collision collaboration in a wireless communication system including at least two Wireless Regional Area Networks (WRANs) with overlapping service areas that employ dynamic frequency hopping is provided. The method includes performing, by at least one Consumer Premise Equipment (CPE) located in an overlapping portion of service areas of at least two WRANs, spectrum sensing and feeding idle channel information back to respective Base Stations (BSs) of the at least two WRANs, broadcasting, by each of the at least two WRANs, a pre-occupation announcement message for a qualified idle channel, and determining, by a WRAN with the highest priority of the at least two WRANs, a time resource allocation for WRANs in a channel collision state of the at least two WRANs. The method addresses problems, such as a large delay and impaired wireless access due to an absence of an idle channel for adjacent WRANs, may be avoided, while the WRANs may maintain their QoSs. Therefore, transmission power of a WRAN during non-operation period may be conserved.
    • 提供了一种用于无线通信系统中的基于时分的信道冲突协作的方法和系统,所述无线通信系统包括具有重叠服务区域的至少两个无线区域网络(WRAN),所述无线区域网络采用动态跳频。 该方法包括由位于至少两个WRAN的服务区域的重叠部分中的至少一个消费者场所设备(CPE)执行频谱感测并将空闲信道信息反馈回至少两个WRAN的相应基站(BS) ,所述至少两个WRAN中的每个WRAN广播合法的空闲信道的预占用通告消息,并且由所述至少两个WRAN中具有最高优先级的WRAN确定信道中的WRAN的时间资源分配 至少两个WRAN的碰撞状态。 该方法可以避免由于相邻WRAN不存在空闲信道而导致的大延迟和无线接入受损等问题,而WRAN可以维持其QoS。 因此,WRAN在非工作期间的发射功率可以被节省。

    • The present invention provides a method for transmitting pilots in a multi-carrier wireless transmission system. A wireless time-frequency transmission block is composed of N consecutive OFDM symbols in time domain and M consecutive physical sub-carriers in frequency domain, N and M are integers those are greater than or equal to 1. The method includes: partitioning the wireless time-frequency transmission block into several areas, and determining the position of pilots, of which the total number is a preset number, according to the time-frequency domain balancing principle of pilots of various antennas in various areas; inserting pilots at the pilot positions of each antenna corresponding to the antenna for transmission. In accordance with the present invention, the simultaneous transmission of multiple antennas is supported in a wireless time-frequency transmission block of a multi-carrier wireless transmission system.

    • A method of targeted online advertising provides to a user advertisements that meet the user preferences. The method stores user information of users, organize the users into user layers, identifies the stored user information of a visiting user based on a user identifier, and identify a target user layer associated with the visiting user. The method then determines a targeted advertisement type for the visiting user based on the favorite advertisement type of the target user layer and the user information of the current visiting user, and accordingly selects a targeted advertisement to be presented to the visiting user. The user information of the visiting user and the related user layer(s) are updated with the new user information including the records of the user's visit activities. The method provides targeted ads to users, and improves the click rates and the efficiency of the online advertisements.
    • 目标在线广告的方法向用户提供满足用户偏好的广告。 该方法存储用户的用户信息,将用户组织成用户层,基于用户标识识别访问用户的存储的用户信息,并且识别与访问用户相关联的目标用户层。 该方法然后基于目标用户层的喜好广告类型和当前访问用户的用户信息确定访问用户的目标广告类型,并且因此选择要呈现给访问用户的目标广告。 访问用户和相关用户层的用户信息用包括用户访问活动的记录的新用户信息来更新。 该方法向用户提供有针对性的广告,并提高点击率和在线广告的效率。
